This invention relates to atsoundgreproducing system, andmoreparticularly to portable phonographs wherein thepick-up is united ;withthe driving motor of the turntable, a stopping device and with furtherappliancesinacase or cabinet to form a readily3portable unit.;;= u vPortable phonographs are known in which? the turntable is so. unitedwith theylid that, when the case is opened the turntable andpick-up.;are accessible for manipulation. These systems are, howeverrather, heavy-by reason of the many componenttmembers. 1 H

In addition, it is known to use a turntable of a table model typephonograph asa lid for the case. In this wellknown construction theturntable remains, however, seated on thedriving and, supporting spindleeven when acting as a lid so that the turntable cannot closethe case-ina dustfree manner for constructional reasons. .,This construc 'on istherefore not well adaptedfor portable sets.

The invention has'f for its Iobject to provideia portable phonographinwhich the lid of the case also acts as a turntable and in which asatisfactory dust-free closure of the case can be obtained.

According to the invention, the turntable, when being used as a cover,is removed from the supporting shaft.

This may be ensured for example by equipping the said supporting spindlewith a detachable top which when the apparatus is being closed isremoved between turntable and bearing.

According to the invention, the supporting shaft of the turntable ispreferably arranged eccentrically in the case. Thus, when records arebeing played the lid occupies a place on the case different from thatwhen the case is shut so that it is possible to meet constructional re-1 quirements as regards both the lid and the turntable.

One embodiment of the invention particularly serving this purposecomprises a phonograph system housed in a cylindrical case whosecylindrical wall is provided with a handle. In this case, the lid has acylindrical closing edge and a circular upper surface which is suited toserve as a turntable.

In order that the invention may be clearly understood and readilycarried into effect it will now be described more fully with referenceto the accompanying drawing, whilst at the same time further features ofthe invention will be set out.

Fig.2 is a plan thereof 7 showing. the lid while being used as aturntable. I I

Referringto the figures, I2 designates the cylindrical boxwhich servesas a case or cabinet forthe phonograph system. i On the upper side, thatis to say on thefside where the turntable and the pick-up l 4 arearranged, this boxis closed by a1 circular lid Ill providedwithcylindrical edges!) closing around the box l2. On its inside surfacethelid is provided at the centre with, a hub i 'l comprisinga conicalaperture. This apertureii' 'fitsaroundthe conical end of a spindle l9.This spindlegwhicliis arranged eccentrically in thejb'ox 'IEnearthewall, only serves to support theturntable ill. The driving force issupplied from a smallfelectric motor 20 arranged below the mounting.plate .l5. The drive fiseifected by meah's of'a smallfriction roller I8on the cylinqriesi edgejoi, the turntable l0. l.

In order that in the use asfa turntable the cylindrical" sides of thelid H) may be passed through the apparatus a cylin'drical'slot I6 isformed in the mounting plate I5. This slot extends on both sides intothe outer wall 12 so that the turntable l0 can turn outside theapparatus in an unhampered manner.

In addition, the space below the mounting plate l5 may be used forhousing the switching-off mechanism and also any accessories such as theamplifier l1 associated with the apparatus. The space below it isarranged as space for storing flexible leads and also some records.These records 2| are resiliently pressed against a lowered part of thebottom plate 23 of the apparatus by means of three small resilient, e.g. spring-pressed rods l3 having bent-over ends.

In order to facilitate the carrying of the apparatus in the closedcondition the box I2 is provided on the cylindrical circumference with aleather handle 22.

The term phonograph as used throughout this specification and theappended claims is intended to cover sound recording as well as soundreproducing systems.

Having now described our invention, what we claim is:

1. A phonograph, comprising in combination,

. a case, a combination cover and turntable member removably associatedwith said case, a flange on said member whereby to fit it concentricallyover said case during service as cover, a centric hub on said member formounting it rotatably in said case during service as turntable, a topplate in said case, a spindle eccentrically mounted in said top platefor supporting said hub, a channel in said top plate and extendingthrough said case wherein to accommodate said flange in its eccentricposition, and a drive member extending into said channel to act on saidflange.

2. A phonograph, comprising in combination, a vertically cylindricalcase, a circular combination cover and turntable member removablyassociated with said cylindrical case, -a circumferential flange on saidmember whereby to fi-t it com centrically over said cylindrical caseduring service as a cover, a centric hub on said member for mounting itrotatably in said base during service as turntable, a top plate in saidcase, a spindle eccentricaliy mounted in said :top :plate for supportingsaid hub, a channel .in said top plate and extending in an are throughsaid-case wherein to accommodate said flange in its eccentric position,and a drive member extending into said channel to act on said flange.

3. A phonograph, comprising in combination, a vertically cylindricalcase, *a-circular combination cover and turntable member removablyassociated with said cylindrical case, a circumferential flange on saidmember whereby to fit -it concentrically over said cylindrical caseduring service'as a cover, a centric hubon said member for mounting itrotatably in said case during service as turntable, atop plate in saidcase, a spindle eccentrically mounted in said top plate for supportingsaid 'hub, a channel in said top plate and extending in an are throughsaid case wherein to accommodate said flange in its eccentric position,a drive member extending into said channel to act on said flange, and apick-up arm pivotally mounted on said top plate outside the arc of saidchannel whereby said pick-up arm may be positioned beneath saidcombination cover and turntable member when said member is in service asa cover and above said combination cover and turntable when said'meniberis in service as a turntable.

4. A phonograph, comprising in combination, a case, a combination coverand turntable member .removably associated with said case, a flange onsaid member whereby to flt it concentrically over said case duringservice as a cover, a centric hub on said member for mounting itrotatably in said case during service as turntable, a top plate in saidcase, a spindle eccentrically mounted in said top plate ior supportingsaid hub, a channel imam top piateanu extending through said casewherein :to accommodate said flange in its eccentric position, a drivemember extending into said channel, and-a friction roller on said drivemember for engagement with said flange.
